[A case of hemorrhage from varices of an interposed jejunum after choledochojejunostomy treated successfully by endoscopic injection using α-cyanoacrylate monomer].

A 73-year-old woman was admitted with gastrointestinal bleeding. She had undergone pylorus-preserving pancreaticoduodenectomy, hepaticojejunostomy and pancreatojejunostomy for pancreatic cancer a year earlier. Gastrointestinal endoscopy revealed bleeding from varices in an interposed jejunum. Enhanced CT showed an extrahepatic portal venous obstruction and cavernous transformation of the portal vein, which were complications of these operations. We performed endoscopic injection using α-cyanoacrylate monomer for the varices. After 4 treatments, the bleeding stopped. We concluded that endoscopic injection using α-cyanoacrylate monomer was effective and useful treatment for bleeding from hepatopetal varices, including cavernous transformation of the portal vein. This method is also useful in emergency situations.

Adsorptive depletion of elevated proinflammatory CD14+CD16+DR++ monocytes in patients with inflammatory bowel disease.

BACKGROUND: In human blood, two monocyte populations exist, CD14(++)CD16(-) classical monocytes and CD14(+)CD16(+) proinflammatory monocytes, which account for about 10% of total monocytes, but can expand to promote inflammatory conditions. CD14(+)CD16(+) monocytes produce large amounts of inflammatory cytokines including TNF-alpha and IL-1. Adacolumn adsorptive carriers adsorb from the blood in the column most of the monocytes/macrophages and granulocytes and this has been associated with clinical efficacy in patients with active inflammatory bowel disease (IBD). This study was to investigate the CD14(+)CD16(+) monocyte profile in patients with IBD and the impact of Adacolumn on this proinflammatory phenotype. METHODS: A total of 58 patients with ulcerative colitis (UC, N = 37) or Crohn's disease (CD, N = 21) together with 11 healthy controls were included in this study. Peripheral blood CD14(+)CD16(+) monocytes were determined by three-color immunofluorescence and flow cytometry. RESULTS: The percentage of CD14(+)CD16(+) monocytes in patients with active CD was significantly (P= 0.0089) higher than the level in the control group, in patients with quiescent CD (P= 0.0419) or quiescent UC (P= 0.0063). Further, the percentage of CD14(+)CD16(+) monocytes in patients with active UC who were on prednisolone (PSL) was less than the level in those not on PSL (P < 0.0001), thus PSL might have a suppressive effect on CD14(+)CD16(+) monocytes. Patients with active IBD were each given up to 10 Adacolumn granulocye/monocyte adsorption (GMA) sessions over an 8-wk period. The percentage of CD14(+)CD16(+) monocytes decreased dramatically (P= 0.0077 in UC and P= 0.0117 in CD) compared with entry levels. CONCLUSIONS: A significant reduction in peripheral CD14(+)CD16(+) monocytes by GMA should mitigate the inflammatory drive and contribute to the clinical efficacy of this procedure. Reduction of CD14(+)CD16(+) monocytes by corticosteroids was also seen. Hence, corticosteroids should enhance the efficacy of GMA. This is the first report on CD14(+)CD16(+) monocytes being decreased by Adacolumn GMA in patients with IBD.

[A case of jejunal perforation in gallstone ileus].

Gallstone ileus is a rare but important cause of small bowel obstruction in the geriatric population. A 65-year-old man with a twenty year history of cholecystolithiasis was admitted to our hospital with abdominal pain and vomiting. Physical exams showed abdominal defence and rebound tenderness. A plain abdominal X-ray suggested a small bowel obstruction and pneumobilia. CT scan revealed a 2.5-cm gallstone at the jejunum and air in the biliary tree. The patient underwent a emergency laparotomy based on a diagnosis of panperitonitis with a perforation associated with gallstone ileus. Operative findings revealed a jejunal perforation and a impacted stone on the anal side of perforation. Enterolithotomy and jejunal resection were performed with cholecystectomy and repairment of the cholecystoduodenal fistula.

Effects of adacolumn selective leukocytapheresis on plasma cytokines during active disease in patients with active ulcerative colitis.

AIM: To investigate the relationship between ulcerative colitis (UC) clinical activity index (CAI) and circulating levels of IL-1ra, IL-10, IL-6 and IL-18. METHODS: Blood levels of IL-1ra, IL-10, IL-6 and IL-18 were measured in 31 patients with active UC, the mean CAI was 11.1, ranging from 5-25; and 12 healthy individuals as controls. Patients were given granulocyte and monocyte adsorptive apheresis (GMA) with Adacolumn. Leucocytes which bear the FcgammaR and complement receptors were adsorbed to the column leucocytapheresis carriers. Each patient could receive up to 11 GMA sessions over 8 wk. RESULTS: We found strong correlations between CAI and IL-10 (r = 0.827, P < 0.001), IL-6 (r = 0.785, P < 0.001) and IL-18 (r = 0.791, P < 0.001). IL-1ra was not correlated with CAI. Following GMA therapy, 24 of the 31 patients achieved remission and the levels of all 4 cytokines fell to the levels in healthy controls. Further, blood levels of IL-1ra and IL-10 increased at the column outflow and inflow at 60 min suggesting release from leucocytes that adhered to the carriers.

Ulcerative colitis in monozygotic twin sisters.

We present a rare occurrence of woman monozygotic twins with ulcerative colitis (UC). A 21-year-old woman came to our hospital because of diarrhea, abdominal pain and hematochezia. We diagnosed this case as proctitis type UC by endoscopic and histological findings. Six months later, her twin sister developed total colitis type UC. Both twins had HLA-A24, B52, DR2, and DQ1 serological types, and had DRB1*1502 DNA type, previously shown to be associated with UC. This case report suggested an association of genetic factor together with environmental factors in the etiology for UC.

Three cases of liver injury caused by Sennomotokounou, a Chinese dietary supplement for weight loss.

Dietary supplements have become very popular worldwide because they are believed to be safe with few side effects. Here, we report three cases of liver injury caused by Sennomotokounou, a Chinese dietary supplement for weight reduction. All patients developed acute hepatotoxicity and recovered spontaneously after withdrawal of dietary product. This product contains fenfluramine, n-nitroso-fenfluramine, and dried thyroid tissue powder. In Japan, the regulatory agency for drug and food safety received 120 reports of hepatotoxicity associated with Sennomotokounou between 2000 and 2002. Physicians should inquire about the use of dietary supplements whenever patients present with unexplained acute liver dysfunction.

Curcumin maintenance therapy for ulcerative colitis: randomized, multicenter, double-blind, placebo-controlled trial.

BACKGROUND & AIMS: Curcumin is a biologically active phytochemical substance present in turmeric and has pharmacologic actions that might benefit patients with ulcerative colitis (UC). The aim in this trial was to assess the efficacy of curcumin as maintenance therapy in patients with quiescent ulcerative colitis (UC). METHODS: Eighty-nine patients with quiescent UC were recruited for this randomized, double-blind, multicenter trial of curcumin in the prevention of relapse. Forty-five patients received curcumin, 1g after breakfast and 1g after the evening meal, plus sulfasalazine (SZ) or mesalamine, and 44 patients received placebo plus SZ or mesalamine for 6 months. Clinical activity index (CAI) and endoscopic index (EI) were determined at entry, every 2 months (CAI), at the conclusion of 6-month trial, and at the end of 6-month follow-up. RESULTS: Seven patients were protocol violators. Of 43 patients who received curcumin, 2 relapsed during 6 months of therapy (4.65%), whereas 8 of 39 patients (20.51%) in the placebo group relapsed (P=.040). Recurrence rates evaluated on the basis of intention to treat showed significant difference between curcumin and placebo (P=.049). Furthermore, curcumin improved both CAI (P=.038) and EI (P=.0001), thus suppressing the morbidity associated with UC. A 6-month follow-up was done during which patients in both groups were on SZ or mesalamine. Eight additional patients in the curcumin group and 6 patients in the placebo group relapsed. CONCLUSIONS: Curcumin seems to be a promising and safe medication for maintaining remission in patients with quiescent UC. Further studies on curcumin should strengthen our findings.

Gastric outlet obstruction caused by a heterotopic pancreas in a pregnant woman: report of a case.

A 26-year-old Japanese woman who was 23 weeks pregnant presented with nausea, vomiting, and abdominal pain. Gastroduodenal endoscopic examination revealed an oval-shaped submucosal tumor obstructing the gastric outlet at the prepyloric area in the stomach. Magnetic resonance imaging showed a 5-cm cystic tumor and we suspected a degenerated gastrointestinal stromal tumor. No other radiological tests were done because of the associated risks to the fetus. Distal gastrectomy was performed and a histological diagnosis of heterotopic pancreas was confirmed. The patient had an uneventful postoperative course and was discharged 19 days after her operation. She delivered a healthy, full-term male infant 3 months later. This case of an ectopic pancreas obstructing the gastric outlet in a pregnant woman is reported and discussed due to its rarity.

Correlation of serum soluble TNF-alpha receptors I and II levels with disease activity in patients with ulcerative colitis.

OBJECTIVES: TNF-alpha has a major role in inflammatory bowel disease via two receptors, p55 (RI) and p75 (RII) expressed on many cell types, in particular neutrophils and monocytes (GM). Upon activation of these leukocytes, RI and RII are shed into the medium and can neutralize TNF. Accordingly, soluble RI and RII (s-RI/RII) are believed to have potent antiinflammatory actions. Further, in active UC, GM are elevated with activation behavior and recently adsorptive GM apheresis (GMA) in patients with severe UC was associated with a dramatic efficacy. In this study, we investigated the effects of GMA on serum s-RI/RII. METHODS: Thirty-one patients with UC, clinical activity index (CAI) 11.1 were treated with GMA by using the Adacolumn. In the column, leukocytes which bear the FcgammaR and complement receptors adhere to the column apheresis carriers (neutrophils, monocytes, and a small fraction of lymphocytes). One GMA session was 60 min at 30 mL/min and each patient could receive up to 11 sessions over 8 wk. Serum s-RI/II were measured in the blood at the column inflow (peripheral blood, time 0 and 60 min) and outflow at 60 min. RESULTS: Serum s-RI/RII showed strong correlation with CAI, r = 0.849 (p < 0.001) and r = 0.867 (p < 0.001), respectively and were greater than when patients were in remission or the levels in controls (p < 0.001). s-RI/RII at the column outflow were higher compared with inflow (p < 0.05) suggesting that RI/RII were shed from leukocytes which adhere to the carriers. Similarly s-RI/RII were significantly increased in the peripheral blood at the end of the 60 min GMA session compared with time 0. After 11 GMA sessions, CAI fell to remission level in 26 of 31 patients accompanied by falls of s-RI/RII. CONCLUSIONS: The sources of s-RI/RII are believed to be activated monocytes and neutrophils with further release when these leukocytes adhere to the column carriers. s-RI/RII released during GMA should contribute to the clinical efficacy of this procedure.

Adsorptive granulocyte and monocyte apheresis versus prednisolone in patients with corticosteroid-dependent moderately severe ulcerative colitis.

BACKGROUND/AIM: Active ulcerative colitis (UC) is often associated with increased peripheral granulocytes and monocytes/macrophages which show activation behavior and prolonged survival time. Further, mucosal granulocyte level parallels intestinal inflammation and can predict UC relapse. Accordingly, our aim was to see if adsorptive granulocyte/monocyte apheresis (GMA) can promote remission and spare steroid in patients with steroid-dependent (SD) UC. METHODS: 69 SD patients, at the time of relapse, were randomly assigned to groups I (n = 46) and II (n = 23). The mean dose of prednisolone (PSL) was 12 mg/day/patient, CAI (clinical activity index) 9.2 in both groups. Group I patients were given up to 11 GMA sessions over 10 weeks with Adacolumn; in group II, the mean dose of PSL was increased to 30 mg/day/patient. RESULTS: At week 12, 83% of group I and 65% of group II patients were in remission, CAI in group I was 1.7 (p < 0.001) and in group II, 2.5 (p < 0.001). Further, during the 12 weeks of treatment, the cumulative amount of PSL received per patient was 1,157 mg in group I and 1,938 mg in group II (p = 0.001). CONCLUSIONS: GMA appeared to be an effective adjunct to standard drug therapy of moderately severe UC by promoting remission and sparing steroids.

Leukocyte adsorptive apheresis for the treatment of active ulcerative colitis: a prospective, uncontrolled, pilot study.

BACKGROUND AND AIMS: Active ulcerative colitis (UC) is characterized by infiltration of activated granulocytes and monocytes/macrophages (GM) within the large bowel mucosa. GM are major sources of inflammatory cytokines, and in UC they are elevated with increased survival time. We investigated the possibility that reducing the level of these cells might promote remission of active UC. METHODS: Thirty-one patients with active corticosteroid refractory (refractory) UC, mean age of 42 years, duration of UC 6 years, clinical activity index (CAI) of 15, disease activity index (DAI) of 10, and 8 corticosteroid naive patients (naive), mean age of 36 years, duration of UC 2 years, CAI of 11, DAI of 8 were recruited. Each patient was treated with up to 11 cycles of granulocyte and monocyte adsorptive apheresis over 11 weeks by using a 335-mL capacity column filled with cellulose acetate beads that adsorb GM. RESULTS: At week 12, 81% of refractory (CAI, 3; P < 0.001 and DAI, 4; P < 0.001) and 88% of naive (CAI, 1; P = 0.012 and DAI, 3; P = 0.011) patients achieved remission. Early relapse was not a feature, and at 12 months, 26 of 33 patients had maintained their remission. The treatment was well tolerated, and no severe side effects were observed. CONCLUSIONS: The outcome of this study suggests that reduction of circulating granulocytes and monocytes results in alleviation of inflammation and promotes clinical remission in patients with severe active UC that has not responded to intensive corticosteroid treatment. These data suggest that formal controlled studies are warranted.
